' Application filed November 21, 1932. serial N0..643,691.-

This invention relates to the construction and manufacture of double-walled vessels. It relates particularlyto ail improved 1nlet assembly for steam-jacketed kettles and the like.

1 In the past, particularly incertain localities, diliiculties have been encountered in-the operation of steam-jacketed kettles and other As a result of this deterioration it sometimes happens that a wall failure occurs,-necess1tatmg replacement or expensive repairs long before the end of the normal useful life of vessels of this type. j

The primary object of my invention is to provide an inlet assembly for double-walled vessels which protects at least one of the walls ofthe vessel from deteriorationby erosion,

corrosion, localized overheating, and analogous destructive factors.

A second object is to provide an improved j inlet assembly for jacketed vessels which is economically constructed and assembled, and

l i as quiet in operation. Y Y

My invention has for further objects such other operative advantages and results as are found to-obtain in the structure described I hereinbelow with reference to the accompany- III ing drawing, in which: 1

Fig. 1 is an elevational view, with parts broken away, of a steam-j acketed kettle. with my improved inlet assembly in place there- Fig; 2 is an enlarged sectional view of th inlet assembly applied as in Fig. 1; a

Fig. 3 is a vertical sectional view of a preforred form of the tubular inlet member ,or nozzleemployedi'n'my inlet assembly;

Fig. l is a topplan view of the inlet member shown in Fig. 3; and a Fig. 5 is another, vertical sectional view of a portion of the inlet-member, taken on the line VV in Fig. 3. I

Referring to the drawing, in which like reference numerals have been used throughout to denote like parts, my improved inlet 1 under which it is held in place.

assembly consists essentially of a tubular in- ALUMINUM COOKING UTENSIL COMPANY, OF NEXV KENSINGTON, P ENNSYLVANI A,

let member or nozzle 1, a concave inner baffle plate 2 provided with a centering pin or guide pin 4, and an outer ballle plate 6 which may sometimes be omitted. The inner bafile or plate Qis held in a fixed position relative to the inlet member 1 and the inner wall or shell 7 of the vessel by the guide pin 4:, which "preferably extends through the plate 2 and 1s connected thereto by welding or brazing 8, J

or other suitable connecting means. a The pin .4: extends outwardly from the surface of the plate and through an aperture 10 which is preferably centrally disposed in a bridge element 11 extending across the orifice or discharge opening 12 in the nozzle 1. The radius of curvature of the plate 2 is preferably less than the radius of curvature of the portion of the inner wall 7 which it covers, to give the plate a resilientcharacter, and when this construction is employed all tendency for the platetojvibratenoisilyor chatter during use is eliminated because of the tension The baffles 2 and 6 are both preferably circular in form, butmay be elliptical or of other suitable shape.

When the lower or outer baflle plate; 6 is employed, it is'preferably applied directly to the inner surface of the outer shell 14 of? the vessel and in close contact therewith, as shown. This plate is formed with a central aperture coinciding with the aperture in the outer shell through which steam or other fluid is admitted, and the edge 15 of the plate aperture may conveniently be spun or otherwise turned down around the edge of the shell aperture to secure the plate 6' in the desired position. Other means ofholding the plate in position may be substituted ifpreferred, however. An internally threaded member 16, in which the nozzle 1 seats, is welded or otherwise secured to the outer shell surrounding the inlet aperture. V

. The baffle plates 2and/or 6 may be-fabrila catcdfrom the same metal as the vessel itself, or from a different metal. The metal selected for this purposein any given case depends on the conditions under which the vessel is to be used and the nature of the de-' structive factors encountered,- i. e., whether and nature of the fluid used in the jacket, and

the amount and'nature of the solids -conmade of aluminum and provided with hard copper baffles give very good results.

One feature of my invention is that the assembly of a double-walled vessel embody-.

ing the improved inlet is very simple. Prior to sealing the outer wall or jacket 14: to the inner wall or kettle 7, the outer battle 6 is applied, if it is to be used, and the inner 'baffle 2 is inserted between the walls with the guide pin 4.- extending through the inlet openmg in the outer wall. No welding or other securing of the bafile 2 is necessary. After the jacket is secured in place, the nozzle 1 is screwed into the seat or socketlfi, care being taken that the guide pin 4 passes through the aperture 10 in the bridge 11 across the nozzle orifice 12. lVhen the nozzle is screwed tightly into place, the bridge member l-l presses against the portion of the baffle 2 sur rounding the guide pin l, and holds the edges of the baflie tightly against the inner wall 7 of the vessel. The completed vessel is then customarily mounted on legs or a stand 18, and is ready for use. When steam or other fluid is admitted to the acket through the nozzle 1, it strikes the baffle 2 and is thus prevented from impinging directly on the inner wall 7. The outer Wall is also protected by the baffle 6. When the bridge member 11 has the preferred form shown in the drawing, the nozzle discharge orifice 12 is divided into two angularly disposed orifices. As a result the entering fluid is diverted from path normal to the surface of the baftle'2 and the inner wall 7, and the life of thebal'l'le and the vessel walls is therefore further prolonged.

WVhile my invention has been described with special reference to a preferred embodiment thereof, it is to be understood that this embodiment may be variously modified within the scope of the appended claims.

What I claim 1s:

1. In a double-walled vessel, a detached baffle plate positioned between the walls to protect the inner wall and having a guide pin secured thereto and extending through the outer wall.- 1

2. In a double-walled vessel, a baffle plate positioned between the walls and partially in contact with the inner wall and having a substantially rigid guide pin extending from its outer surface through an aperture in the outer wall of the vessel.

3. In a'doublewalled vessel, a curved baffle plate positioned between the walls with its edge in contact with the inner wall, said baflle having a smaller radius of curvature than the portion of the inner wall coveredthereby and bein held against the inner wall by a member adjustably attached to the outer wall and bearing against said baffle substantially at its wall, a guide pin secured substantially at the center of said baflle and extending outwardly therefrom, and a member supported by the outer wall and providedwith 'an aperture adapted to receive said guide pin to holdsaid baffle plate in the desired position relative to said member. V

6. In a double-walled vessel, a baflie plate between the walls provided with a guide pin secured thereto and extending outwardly therefrom through an aperture in the outer wall, and an inlet member mounted in said aperture and engaging said guide pin to llCilCl re asaid baffle plate in the desired position tive to said inlet member. a a

7. In a double-walled vessel, an externally convex substantially circular baifle plate p0- sitioned between the walls with its edge against the inner wall, a guide pin secured substantially at the center ofsaid bafi'le plate and extending outwardly therefrom, and a tubular inlet member extending through an aperture in the outer wall and having at its inner end means for engaging said guide pin and pressing said battle plate-against the inner. wall. a i

8. In a double-walled vessel, an externally convex substantially circular baffle plate positioned between the walls with its edge against the inner wall, a guide pin securedsubstantial-ly at the center of said baflie-plate and extending outwardly therefrom, and anozzle adjustably mounted to extend through an aperture in the outer wall, said nozzle having at its inner end an element provided with an aperture through which said guide pin extends, said element holding saidbafile against he inner wall.

9. An inlet assembly for jacketed vessels, comprising a tubular inlet member extend ing through an aperture in the 'outer wall of the vessel and provided at its inner end with an element having a port therein,-an exter nally convex baffle with an outwardly extending guide pin secured thereto and extending through said port, said baflie being held against tl e inner wall of thevessel by the said element on the inner end of the inlet member, and-a second bafiie plate covering the inner surface of the outer wall of the vessel adja-- cent the aperture therein. 7 v 7 In testimony whereof I hereto afixmy. signature. i
